When you need a police report first: the tow that has to wait
The mechanics of getting the report vary by emirate. In Dubai, minor accidents with no injuries are reported through the Dubai Police app, and you are expected to move the cars out of traffic first; blocking a lane for a scratch can itself attract a fine. In Abu Dhabi, Saaed units attend and document accidents. In Sharjah, Rafid performs the same role. In the Northern Emirates, you call 999 and wait for direction. Photograph everything before anyone moves: positions, damage, plates, the road context. Once the report or reference number exists, book the tow and tell the vendor it is an accident recovery, because a car with broken suspension or deployed airbags loads differently to a car that simply will not start.
One scenario sits in between: single-car damage with no other party, a kerbed wheel that snapped a control arm, a pothole impact, hitting a road object. If you intend to claim on comprehensive insurance, you still need a report. If the damage is minor and you will pay for the repair yourself, you can usually treat it as a breakdown, but when in doubt, get the reference number; an insurer can reject a claim weeks later for a missing report you can no longer obtain.
